This is a false positive, as you can still compile and run your application fine. There are two accepted workarounds to remove Android Studio from reporting this as an error. If you cast all getClass calls with Object, it will remove the error. There is a better workaround that will remove the erroneous error that does not require you to modify your code.

Steps

Open Finder

Navigate to the target SDK’s source. For example, if you are targeting API 19, navigate to $ANDROID_HOME/sources/android-19/java/lang/

Open Object.java in a text editor (such as Atom or TextWranger)

Scroll to public final native Class<?> getClass(); (line 241 for API 19)

Remove the unbounded wildcard so the line now looks like: public final native Class getClass();
